Influenced by Anonymous Others: Effects of Online Comments on Risk Perception and Intention to Communicate

College students in China during initial COVID-19 pandemic: Role of social media on attitudes toward preventive measures

Objective: To examine the direct and indirect associations (through risk perceptions) between college students' social media use and their perceived importance of COVID-19 preventive measures. Participants and Method: 1,353 undergraduate students in China completed an online survey in 2020 Spring. Results: Participants reported high reliance on social media for COVID-19 updates, which was positively associated with perceived importance of preventive measures. Information-oriented social media use was associated with higher perceived importance of preventive measures not only directly but also indirectly via increased cognitive and emotional risk perceptions. Social-oriented media use, on the other hand, had a negative direct association with perceived importance of preventive measure as well as a positive indirect association via emotional risk perception. Conclusions: This study shows that social media are important information sources for college students during the early stage of the pandemic and their response to the pandemic was related to social media use.

Fighting Fire or Fighting War: Examining the Framing Effects of COVID-19 Metaphors

Metaphorical language describing the COVID-19 pandemic as a war has been pervasive in public discourse (e.g. "the pandemic is a war," "the virus is an enemy," and "the vaccine is a weapon"). This study employs an online survey experiment (N = 551 U.S. adults) to examine the impact of war metaphors compared to non-metaphorical literal frames and fire metaphors (e.g. "the pandemic is a wildfire"). War metaphors exhibited little advantage over literal frames across a variety of desirable outcomes (i.e. the adoption of pro-health behaviors against COVID-19, perceived solidarity and collective responsibility to curb the pandemic, and intentions to discuss and share the health news with others). However, this study revealed some benefits of war metaphors over fire metaphors. Compared with fire metaphors, health news featuring war metaphors increased both positive emotions and perceived threats of COVID-19, which in turn promoted pro-health behaviors against COVID-19 and perceived solidarity to cope with the public health crisis. Moreover, positive emotions in response to war metaphors also indirectly encouraged the retransmission of science-based COVID-19 health news. This study thus showcased the benefits and limitations of war metaphors and revealed the mediating roles of perceived threats and positive emotions in explaining war metaphorical framing effects. Implications of using war and fire metaphors for communicating about public health crises are also discussed.

Exploring the effects of cannabis health warnings on protective health intentions among US adults in legal recreational states

BACKGROUND

As cannabis policy trends toward liberalization, assessing cannabis health warning effects becomes increasingly important. This study investigated underlying mechanisms accounting for the effectiveness of cannabis health warnings on protective health intentions.

METHOD

A sample of 1,095 adults (21+) living in legal recreational US states who reported using cannabis in the past 12 months participated in an online experiment. Participants were randomly assigned to view cannabis health warnings that described risks of impaired driving, mental health, and smoke exposure and varied pictures and text (vs. text-only) attributes in warnings. Outcomes were message reactions (cognitive elaboration, fear, and hope), attitudes and beliefs (perceived severity of cannabis harms and perceived susceptibility to cannabis harms, and perceived response and self-efficacy to prevent cannabis harms), and protective health intentions (information-seeking about cannabis health effects and having interpersonal discussions about cannabis harms with family, friends, and medical professionals).

RESULTS

MANCOVA results showed no significant differences between text-only vs. pictorial attributes on protective health intentions; thus, warning conditions were controlled and analyzed using structural equation modeling (SEM). SEM results showed that attention to cannabis health warnings (text-only or pictorial) elicited higher cognitive elaboration, fear, and hope-an emotion associated with coping actions that motivate positive expectations of future events. These outcomes, in turn, were associated with greater perceived severity and susceptibility and greater perceived response efficacy, respectively. Hope, perceived severity, and perceived response and self-efficacy were independently associated with greater intentions to seek information about cannabis health effects and to discuss cannabis health harms.

CONCLUSION

Attention to warnings impacted emotions, attitudes, and protective health intentions. Fear is commonly associated with health warning effects, and our results suggest that hope is also an important factor. This research contributes to understanding the effects of cannabis health warnings and can inform regulatory agencies that mandate warnings on cannabis products.

Preventing the COVID-19 Outbreak in Vietnam: Social Media Campaign Exposure and the Role of Interpersonal Communication

The present study focused on the success story of Vietnam's ability to control the COVID-19 outbreak in the early stages to examine the associations between exposure to the Vietnam Ministry of Health's COVID-19 prevention social media campaign messages, interpersonal communication, attitudes, perceived norms, self-efficacy, and intentions to stay at home. A cross-sectional survey was conducted with residents in Ho Chi Minh City (N = 360). Results from mediation analyses indicated that interpersonal communication mediated the effect of social media campaign exposure on intentions to stay at home. Moreover, interpersonal communication shaped injunctive norms and self-efficacy that were conducive to behavioral intentions. These results underscored the need to leverage the power of social media and interpersonal communication in public health campaigns to prevent infectious outbreaks.

Women's empowerment and elective cesarean section for a single pregnancy: a population-based and multivariate study in Vietnam

Background

Women’s empowerment, and maternal and neonatal health are important targets of the Sustainable Development Goals. Our objective is to examine the relationship between women’s empowerment and elective cesarean section (ECS), focusing on Vietnam, a country where the use of CS has increased rapidly in recent decades, which raises public health concerns.

Methods

We hypothesized that in the context of the developing biomedicalization of childbirth, women’s empowerment increases the use of ECS due to a woman’s enhanced ability to decide her mode of delivery. By using microdata from the 2013–2014 Multiple Indicator Clusters Survey, we conducted a multivariate analysis of the correlates of ECS. We studied a representative sample of 1343 institutional single birth deliveries. Due to higher ECS rates among multiparous (18.4%) than primiparous women (10.1%) and the potential interaction between parity and other correlates, we used separate models for primiparous and multiparous women.

Results

Among the indicators of women’s external resources, which include a higher level of education, having worked during the previous 12 months, and having one’s own mobile phone, only education differed between primiparous and multiparous women, with a higher level among primiparous women. Among primiparous women, no resource indicator was significantly linked to ECS. However, considering women’s empowerment facilitated the identification of the negative impact of having had fewer than 3 antenatal care visits on the use of ECS.

Among multiparous women, disapproval of intimate partner violence (IPV) was associated with a doubled likelihood of undergoing ECS (odds ratio = 2.415), and living in an urban area also doubled the likelihood of ECS. The positive association with living in the richest household quintile was no longer significant when attitude towards IPV was included in the model. In both groups, being aged 35 or older increased the likelihood of undergoing ECS, and this impact was stronger in primiparous women.

Conclusions

These results underline the multidimensionality of empowerment, its links to other correlates and its contribution to clarifying the influence of these correlates, particularly for distinguishing between medical and sociocultural determinants. The results advocate for the integration of women's empowerment into policies aimed at reducing ECS rates.
